Tree Data

The Dublin Tree map initiative is an important way to identify and assess the city’s urban forest. the first step is to map the tree species we have throughout Dublin city, and then identify where deficits might be.

Mapping Green Dublin has mapped all the trees across Dublin and they have been uploaded on to the CURIO website. Information about Curio can be found on the webpage,, which also contains links to the app on the Google Playstore and Apple Appstore.

The Dublin Tree Map initiative is a collaboration between Dublin City Council’s Parks, Biodiversity and Landscape Services; the School of Geography at University College Dublin and Mapping Green Dublin partners whose research is funded by the EPA and Breadboard Labs., designers of the Curio app.

Our mapping exercise shows that:

  • There are approximately 300,000 trees in the Dublin City Council area, with a clear concentration along some streets, in a few neighbourhoods and in public parks, especially Phoenix Park. 
  • The tallest trees (and by implication the most mature) are located in parks and in some neighbourhoods. There are relatively few large and very large trees in the city centre.
  • The distribution of trees across DCC is very uneven. Most are located on private lands, especially in the low-density suburbs on the north and south side of the city. By comparison, apart from public parks, there are relatively few trees in the city centre.
  • Tree density varies across the city and we have classified it into six classes from low to high, around the average of 25 trees ha-1. Low to very-low values are found where the landscape is mostly paved or where there is an extensive area of grass. The paved area is associated with the built-up area extending from the eastern port areas, through the city centre, towards industrial locations in the west of the city. 
  • The neighbourhoods of highest tree density are in Donnybrook and Clontarf near the coast and around Phoenix Park.
